The double-outlet right ventricle is a rare congenital ventriculoarterial malformation reported only in certain cattle breeds. We describe this rare and complex congenital cardiac malformation observed in a 10-day-old male Chianina calf. Clinical examination showed tachycardia, tachypnea, jugular pulses, cyanotic mucous membranes and a right apical systolic murmur. Transthoracic echocardiography revealed severe dilation of the right-sided cardiac chambers with a markedly hypoplastic left ventricle. Both aorta and pulmonary artery leaving the right ventricle in parallel alignment with the tricuspid valve were suggestive of a dual-outlet right ventricle. Interventricular and interatrial septal defects were also visualized. Post-mortem examination confirmed the echocardiographic findings. To the authors\u2019 knowledge, a similar complex congenital cardiac malformation has not been reported in calves of the Chianina breed to date.<\/jats:p>","DOI":"10.3390\/ani11020318","type":"journal-article","created":{"date-parts":[[2021,1,27]],"date-time":"2021-01-27T12:20:26Z","timestamp":1611750026000},"page":"318","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Double-Outlet Right Ventricle in a Chianina Calf"],"prefix":"10.3390","volume":"11","author":[{"given":"Domenico","family":"Caivano","sequence":"first","affiliation":[{"name":"Department of Veterinary Medicine, University of Perugia, Via San Costanzo 4, 06126 Perugia, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria Chiara","family":"Marchesi","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medicine, University of Perugia, Via San Costanzo 4, 06126 Perugia, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Piero","family":"Boni","sequence":"additional","affiliation":[{"name":"Veterinary Practice, Via Martiri di Modena 2, 06033 Perugia, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Noemi","family":"Venanzi","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medicine, University of Perugia, Via San Costanzo 4, 06126 Perugia, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Giovanni","family":"Angeli","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medicine, University of Perugia, Via San Costanzo 4, 06126 Perugia, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Francesco","family":"Porciello","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medicine, University of Perugia, Via San Costanzo 4, 06126 Perugia, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8478-8154","authenticated-orcid":false,"given":"Elvio","family":"Lepri","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medicine, University of Perugia, Via San Costanzo 4, 06126 Perugia, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,1,27]]},"reference":[{"key":"ref_1","first-page":"249","article-title":"Incidence of congenital cardiac defects in bovine fetuses","volume":"33","author":"Kemler","year":"1972","journal-title":"Am.
